GeoSage’s software tool, Spectral Transformer for Landsat-8 Imagery, has been enhanced to include new functions towards automated image feature extraction.

The changes are built upon the existing tool, so with two button clicks, a user is able to rapidly perform image-band combinations, image stretching and image pan-sharpening, and produce colorful, detail-rich imagery composites at 30m and 15m resolutions.

generic function to calculate 56 band ratios, with 3 types of outputs.

The 3 types of outputs are automatically generated by the software. Each is a single-band GeoTIFF file, ready to be displayed in Windows Photo Viewer, GIS and remote sensing software, or Google Earth Pro.

Third output: 8-bit Byte data type, a binary image to show classified features after a user-defined threshold is applied.

This Landsat-8 image analysis software tool targets geospatial professionals, K-12 students, as well as the general public. It is very easy to use, productive and saves time. To test the new functions, a trial version is available. Updated software user guide and new application demos are also provided.
